The invention relates to the technical field of intelligent traffic information processing, and discloses an intelligent traffic intelligent signal control method which comprises the following steps: step 1, data acquisition: collecting real-time traffic data including vehicle flow, speed and density information; according to the intelligent traffic signal control method and system, secondary queuing caused by insufficient green light duration can be identified according to vehicle detector occupancy data, and in addition, traffic flow control, red wave band setting, road segmented storage of vehicles, traffic paralysis prevention of a congestion area and dynamic trunk line priority green wave band control are carried out in a seriously congested area, so that the traffic efficiency is improved. The vehicle speed and the phase difference are dynamically calculated through traffic big data and are obviously reasonable compared with a static green wave band, key intersection signal timing is optimized, green light time delay and red light time end in advance are determined according to the conditions of arrived vehicles, and therefore the vehicle passing rate of the intersection can be increased, and traffic pressure can be relieved.
本发明涉及智能交通信息处理技术领域,且公开了智能交通智能信号控制方法,包括以下步骤:步骤1、数据采集:收集实时的交通数据,包括车辆流量、速度和密度信息。该智能交通智能信号控制方法,系统也能够根据车辆检测器占有率数据识别因绿灯时长不足而引起的二次排队,此外,严重拥堵区域进入交通流量控制,设置红波带,利用道路分段存储车辆,避免拥堵区域交通瘫痪,动态干线优先绿波带控制,利用交通大数据动态推算车速和相位差,比静态绿波带明显合理,重点交叉口信号配时优化,根据到达的车辆情况,决定绿灯时间延后和红灯时间提前结束,从而有助于提高路口的车辆通行率,缓解交通压力。
